An AC model of a cascode common-source amplifier is shown below. M1 and M2 are biased in saturation mode. The parasitic capacitors in the transistors are included. Determine the poles in frequency response at node A, X, and Y respectively.
How do we determine the overall gain of a cascaded system of AV1, AV2, and AV3 in dB, in absolute What do we do if all the gains are given in dB, absolute and dB
Discuss how you could build a microwave power amplifier with a power rating of 1kW with microwave power transistors with an upper power limit of 100W each. Explain how the speed of an aircraft can be measured by using pulse radar techniques.
Two loads are in parallel with a 1.2kV sinusoidal source. Load 1absorbs 60 kVAR at 0.6 leading power factor. Load 2 draws 90 kW at0.707 lagging power factor. A) How would i find the complex power in polar form
An LVDT is used in an accelerometer to measure seismic-mass displacement. The LvDT and signal-conditioning output is 0.31 mV/mm with a +/-2 cm maximum core displacement.
A 100 MW unit with 0.05 puturbine regulation operates in parallel with a 500 MW unit of identical turbine regulation. For a specific amount of power demand increase, find the ratio of sharing of the load by the units, system frequency is 50 Hz.
